1990 Federal Voting System Standards
States may choose whether to adhere to the voluntary, federal Voting System Standards. Reportedly 42 states do follow the federal standards. Although there are more current standards that were developed by the Federal Election Commission in 2002, it is the 1990 standards to which all voting equipment in use right now in the U.S. are tested, if at all. These standards have not been available online since the FEC adopted the new standards in 2002. Thanks to the good folks at the Electronic Privacy Information Center, the 1990 standards are now available to the public online via the EPIC web site.
